Nope! jm->id specifies the id attribute on the message element, which we
already set. This spec is talking about the id element that is a child of the
<x xmlns='jabber:x:event'> element.
We're definitely in violation of the spec here. I don't think adding an empty
<id> tag would help much, we'd still be in violation of the spec. Really I
think we should only be sending XEP-0022 <composing> messages if we're
replying to a message. We should not send them on the initial message to
someone. And the id tag should contain the value of the id attribute from the
message tag that you received from the other person.
But it's kinda minor. It would be easier to just remove support for XEP-0022,
since it's superseded by XEP-0085 anyway.
